The ICA officer tested positive on Apr 27 when he sought treatment at Tan Tock Seng Hospital for a fever, loss of sense of smell and body aches.

A few days before that, on Apr 23, he had developed a cough and was given two days of medical leave by a general practitioner.

His previous swabs from routine testing, the last being on Apr 22, were negative for the coronavirus.

ICA officer 23号去看GP，给了两天MC（不知是23，24还是24，25）。 然后25号晚上和family members聚餐传了好几个人。
